# TaxJar The TaxJar connector is a [Palantir-provided driver](../../data-integration/foundry-provided-drivers/index.md) for TaxJar. To create a new TaxJar source, follow the [standard setup flow for Palantir-provided drivers](../../data-integration/foundry-provided-drivers/index.md#setup), then use the sections below for TaxJar-specific configuration and networking. For the complete property reference, see the [official TaxJar driver documentation ↗](https://cdn.cdata.com/help/JTK/jdbc/pg_connectionj.htm). :::callout{theme="neutral" title="Beta"} The TaxJar connector is in the [beta](../../platform-overview/development-life-cycle/index.md) phase of development and may not be available on your enrollment. Functionality may change during active development. ::: ## Supported capabilities | Capability | Status | |---|---| | Exploration | 🟡 Beta | | Batch syncs | 🟡 Beta | | Incremental | 🟡 Beta | ## Configuration The properties below are mandatory or recommended. | Property | Required? | Description | Default | |---|---|---|---| | [`APIKey` ↗](https://cdn.cdata.com/help/JTK/jdbc/RSBTaxJar_p_APIKey.htm) | Mandatory | The APIKey obtained from the TaxJar UI. | — | | [`UseSandbox` ↗](https://cdn.cdata.com/help/JTK/jdbc/RSBTaxJar_p_UseSandbox.htm) | Recommended | Whether to connect to the sandbox environment or not. | `FALSE` | ## Networking The table below lists the domains that the source must be able to access to run. For each domain, add a corresponding [egress policy](../../administration/configure-egress/index.md). If the source is hosted on-premises and not directly reachable from Foundry, use an [agent proxy egress policy](../../administration/configure-egress/index.md#agent-proxy-egress-policies) instead. The agent host itself must also be able to reach the listed domains. See [using an agent as a proxy](../../data-connection/agent-proxy/index.md) for details. | Domain | Required | |--- |--- | | api.taxjar.com | If `UseSandbox=FALSE` (default) | | api.sandbox.taxjar.com | If `UseSandbox=TRUE` |
